Python fails -Nonetype object not iterable

jbrobrown · 12-03-2010, 02:03 PM

I have a number of books I have scanned into MS Word format. I save them as HTML and convert to MOBI for use on my Kindle. With Calibre version 7.27 I have started getting errors on about one book in five. These are books that converted OK on earlier versions. Problem still exists on version 7.31 The error mesage is:
Python function terminated unexpectedly
'NoneType' object is not iterable (Error Code: 1)
Traceback (most recent call last):

TypeError: 'NoneType' object is not iterable

I suspect but don't know that the problem may be empty text boxes. These are sometimes hard to see. Any ideas , Thanks

open a ticket and attach one of the files causing this error.

I deleted version 0.7.32 and reloaded calibre 0.7.24. Since I primarily use Calibre to translate MS Word documents to MOBI to use on the Kindle, this is a good clean version.
I have been using Calibre for about 2 1/2 years now and would like to extend my thanks and appreciation for the steady improvement of this product.
